## printcomb
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Write a function that prints, in ascending order and on a single line: all **unique** combinations of three different digits so that, the first digit is lower than the second, and the second is lower than the third.
|
||
|
|
|
||
|
|
These combinations are separated by a comma and a space.
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func PrintComb() {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible program to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
PrintComb()
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
This is the incomplete output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ go run . | cat -e
|
||
|
|
012, 013, 014, 015, 016, 017, 018, 019, 023, ..., 689, 789$
|
||
|
|
$
|
||
|
|
```
|
||
|
|
|
||
|
|
- `000` or `999` are not valid combinations because the digits are not different.
|
||
|
|
|
||
|
|
- `987` should not be shown because the first digit is not less than the second.
|
||
|
|
|
||
|
